Tiny 5X7 SMD form factor
Hermetically sealed for rugged environmental conditions
Extremely wide operating temperature range accommodates harsh
environments
All crystals are processed in-house with tight angle control to assure
best frequency-temperature characteristics
All units are vacuum baked before sealing at 175°C for 16 hours to
eliminate moisture traces and pre-age units for superior stability

Description
Owing to their small size, light weight, and
rugged characteristics, these 5V HCMOS
extended temperature/COTS oscillators
fulfill tasks not previously feasible. They
are used in applications that take advantage
of their extended temperature range and
high performance. Twenty four different
models (with and without tristate) cover
-55°C to +200°C operation and provide
frequency selection from 20KHz to
100MHz. They combine excellent long-
term reliability, loading characteristics, and
superior startup performance.
Typical Applications
Any electronic circuit requiring 5V HCMOS clocking that is exposed to
very high or very low temperatures such as oil drilling or weather
observation equipment
